building2 ... building10, and call the Devices residing on each building DHCP Relay1,
DHCP Realy2 ... DHCP Realy10. Each relay agent Device has its own ID.
The Device residing on the center network acts as a DHCP server, and the DHCP address
pools are bound to the LAN interface with IP address 200.200.200.254/24.
The Devices residing on each building act as the DHCP relay agents. The DHCP relay
agent is enabled on each Device¶s LAN interface. The hosts residing on each building are
connected to the related Device¶s LAN interface respectively, and they will act as clients to
request addresses from the DHCP server. The following table lists the name, relay agent
ID, WAN IP address and LAN IP address for each relay agent Device. Also it lists the IP
address space of each subnet where the client hosts reside.
Name WAN IP address LAN IP Address Client Subnet Relay Agent ID

Table 7-4 DHCP Relay Agent IP Addresses and IDs - Comprehensive Example
In order to ensure that the hosts residing on each building obtain the addresses in the
range of the specified subnet respectively, we need to create ten DHCP address pools on
the DHCP server Device. These DHCP address pools¶ settings are as follows:
Ɣ Every DHCP address pool is bound to the LAN interface.
Ɣ Their pool names are pool1, pool2 ... pool10 respectively.
Ɣ Their starting IP addresses are 192.168.1.2, 192.168.2.2 ... 192.168.10.2
respectively.
